Unofficial Node.js module for the Maxmind GeoIP2 Web Services.

• Changelog
• Node.js
• Maxmind GeoIP2 Web Services
• API documentation

The configuration parameters must be wrapped in an object. This allows the use of spread { ...config, ip: '1.2.3.4' } if you want to keep the main config in a variable. The lookup always returns a Promise.

• Response examples

const geo = require( 'geoip2ws' );

geo( {
  userId:     '12345',
  licenseKey: 'abc678',
  service:    'city',
  ip:         '1.2.3.4',
} )
  .then( console.log )
  .catch( console.error )
;

You need a Maxmind account ID and license key with enough credits for one of their GeoIP web services. You can find both here.

npm i geoip2ws

{
  ip:         '2a02:abc:def::123',
  userId:     '1234',
  licenseKey: 'abc',
  service:    'country',
  timeout:    2000,
}

You can change the endpoint to use a http proxy or target a specific datacenter. Make sure to prefix the hostname with the protocol, i.e. https://.

For the GeoLite2 web service set the endpoint to https://geolite.info.

Errors from the request or API are thrown and can be caught in the Promise.

For API errors the message is prefixed with API: string.
